Has the institution conducted a GHG emissions inventory within the previous three years that includes all Scope 1 and 2 emissions? :
A copy of the most recent GHG emissions inventory:
A brief description of the methodology and/or tool used to complete the GHG emissions inventory:
The GHG emissions inventory follows the Greenhouse Gas Protocol. University activities and the associated emissions are translated into equivalent carbon emissions (CO2e) using the 2014 IPCC Fifth Assessment. Our Utility Manager and Energy Manager prepare GHG report for the State Comptroller's office in compliance with State Energy Conservation Office.
Has the GHG emissions inventory been validated internally by personnel who are independent of the GHG accounting and reporting process and/or verified by an independent, external third party?:
A brief description of the GHG inventory verification process:
We hired DBHMS a consultant and mechanical engineer to validate our Greenhouse gas data.
Documentation to support the GHG inventory verification process:
Gross Scope 1 GHG emissions, performance year:
| Weight in MTCO2e | |
| Stationary combustion | 14,183 Metric tons of CO2 equivalent |
| Other sources (mobile combustion, process emissions, fugitive emissions) | 2,703 Metric tons of CO2 equivalent |
Total gross Scope 1 GHG emissions, performance year:
Gross Scope 2 GHG emissions, performance year (market-based):
| Weight in MTCO2e | |
| Imported electricity | 45,085 Metric tons of CO2 equivalent |
| Imported thermal energy | 0 Metric tons of CO2 equivalent |
Total gross Scope 2 GHG emissions, performance year:
Gross GHG emissions from biogenic sources, performance year:
Does the GHG emissions inventory include Scope 3 emissions from the following sources?:
| Yes or No | Weight in MTCO2e | |
| Business travel | Yes | 2,126.59 Metric tons of CO2 equivalent |
| Commuting | Yes | 49,078.81 Metric tons of CO2 equivalent |
| Purchased goods and services | Yes | 34,065 Metric tons of CO2 equivalent |
| Capital goods | --- | 28,923 Metric tons of CO2 equivalent |
| Fuel- and energy-related activities not included in Scope 1 or Scope 2 | Yes | 12,831 Metric tons of CO2 equivalent |
| Waste generated in operations | Yes | 1,285 Metric tons of CO2 equivalent |
| Other sources | Yes | 1,366 Metric tons of CO2 equivalent |
Total Scope 3 GHG emissions, performance year:
A brief description of how the institution accounted for its Scope 3 emissions:
Key assumptions (listed below) were made to account for Scope 3 emissions.
"University Population – 34,742 Students, 1,432 Faculty and 2,739 Staff
Business travel – air travel for conferences and other events. Assumes 1000 trips (one-way) an average of 1,500 miles.
Employee commuting - based on the average commute in San Antonio of 41 totals miles
50% of Students drive 5 days per week 30 weeks per year
95% of Faculty drive 5 days per week 35 weeks per year
95% of Staff drive 5 days per week 47 weeks per year
Student Travel – students traveling to and from campus at the start and end of the semester (4 times per year)
Air – 5% of the total student population travels 500 passenger-miles
Car – 20% of total population travels an average of 150 passenger-miles
Purchased goods and services – estimated from other university reporting
Capital goods - estimated from other university reporting
FERA – GHG Protocol Quantis tool was used to estimate this number based on Scope 1 and 2 data
Waste generated in operations - estimated from other university reporting"
Has the institution completed an inventory within the previous three years to quantify its air pollutant emissions?:
Annual weight of emissions for::
| Weight of Emissions | |
| Nitrogen oxides (NOx) | 6.82 Tons |
| Sulfur oxides (SOx) | 0.11 Tons |
| Carbon monoxide (CO) | 7.77 Tons |
| Particulate matter (PM) | 30.69 Tons |
| Ozone (O3) | --- |
| Lead (Pb) | --- |
| Hazardous air pollutants (HAPs) | --- |
| Ozone-depleting compounds (ODCs) | --- |
| Other standard categories of air emissions identified in permits and/or regulations | 2.78 Tons |
Do the air pollutant emissions figures provided include the following sources?:
| Yes or No | |
| Major stationary sources | Yes |
| Area sources | Yes |
| Mobile sources | Yes |
| Commuting | Yes |
| Off-site electricity production | Yes |
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
NOx 5.18 from Plant, 1.64 from commuting (estimated) business travel and employee and student commuting.
Methane 2.78 as a standard category estimated from business travel and employee and student commuting.
Gross Scope 2 GHG emissions from purchased electricity (location-based):
Gross Scope 2 GHG emissions from imported thermal energy (location-based) :
